EXP 7: THE FOCAL LENGTH OF A CONVEX LENS BY GRAPHICAL METHOD
ABSTRACT
The report is about the focal length of a convex lens using the graphical method. The aim of the report is to determine the focal length of a convex lens using the graphical method. The focal length of an optical system is a measure of how strongly the system converges or diverges light. The method that was used was experimentation because it is one of the fundamental steps in the scientific method. In addition experimentation is a methodical trial and error procedure carried out with the goal of verifying, falsifying, or establishing the validity of a hypothesis. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Furthermore experimentation was used because it is testable and replicable such that a different person can perform the same experiment and get the same results. In the experiment the focal length was first approximated to obtain a rough value of 10cm, and through experimentation it was found out that the value was obtained for the focal length of the convex lens was 9.08± 0.3cm. The method used for the experiment is the best method as it is accurate because people can follow the same procedure and get the same results. It was concluded that the focal length of a convex lens is 9.8 ± 0.3cm.
